BOOK COVER.

Application filed August 22, 1921. Serial No. 494,195.

To aZZ whom it may cancer n:

Be it known that I, ROBERT JAMES Corn- LAND, a subject of the King of Great Britain, and resident of the city of Toronto, County of York, Province of Ontario, in the Dominion f Canada, have nven ted certain new and usefullmprovemen ts in Book Covers, described in the following specification and illustrated in the accompanying drawings, that form part of the same.

The objects of this invention are to provide a cover of an extremely strong and durablenature which will erfectively protect the leaves of the book and which may be inanufactured at low cost.

The princ ipal feature of the invention consists in re-enforcing the edges of a. cover by rigidly securing to the outer face of a stiff hacking protect-ing strips of a nonnetallic, tough homogeneous material such as vulc-anized bre.

In the drawings Figure l is a perspective view of a cover constructed in acco rdance with this invention. r

Figura 2 is a longitudinal sectional View through the cover shown in Fig. '1.

Figures 3 and 4: are detail sectional views of modified structure&

In order to overcome the difficulties met with in the use of soft multiple ply material such as mill board for the body of book covers, this invention purposes reenforcing such material by securng around its edge a re-enforcing strip of a tough, strong, wear resisting material such as vulcanized fibre. i

In carrying the invention into effect a sheet 1 of mill board or other suitable material of a desired size has placed upon its outer face at the edges a plurality of s'rips 2, 3 and i of vulcanized fibre or similar material and these strips are securcly riveted through the sheet so that the Strength of the fibre will be imparted to the mill board to prevent its bending and cracking and to presenta protective edge which will not disintegrate through wear and the effects of the' atmosphere and time and become soft and,

spongy. i i

A recess is formed in the outer face of the cover by the placing of the strips 2, 3 and tthereon and this is *preferably filled by a suitable board 5 which may be riveted or otherwise Secured rigidly in place and forms a hacking for any suitable form of finishing material. i

In the form of the invention shown in' Figures 1 and 2 a re-enforcing binding 6 of thin homogeneous wear resisting material is placed around the edge of the board l prior to the placing of the strengthening strips 2, 3 and 4 and the whole structure 'is riveted together, the binding strips 6 extending inwardly past the inner edge of the edge strips.

In the form shown in Figure 3 a flat strip 7 of sheet metal or vulcanized fibre is inserted between the board 1 and the edge protecting strips and in the form shown in F igure t the edge strips are formed with a depending fiange 8 to abut the outer edge of the board l.

It will be noted that in the construction as herein described the ordinary laborious and expensive wrapping of the cover is dispensed with and a very strong and durable cover is produced; v

lVhat I claim as my invention is 1- l. A book cover, comprising, a stiff board, a thin strip of reinforcing material covering the outer face of the board at the edge,

a strip of a' rigid wear-resisting material of i lesser width than the aforesaid strip arranged on the outer face of said strip and at the outer edge thereof, said strips and board being rigidly Secured together, and a board secured to the aforesaidboard and fitting between the outer strips and overlapping the reinforcing strip.

2. A book cover comprising a suitable base, strips of thin reinforcng sheet inaterial Secured to the face of said base at the edges, heavier strips of vulcanized fibre of narrower width than said sheet material secured at'the outer edges and on the outer face of said renforcing strips to form a protective edge for the cover, a board arranged between said outer strips, and rivets rigidly securing said strips and boards together.

3.' A book cover comprising a suitable base, strips of thin sheet, wear resisting material securedto the face of said board and lapped around the edge thereof, thick strps of a tough protective material rigidly secured to the face of said sheet strips and to the board and forming a 'protective' edge frame for` the cover, and a filling panel oVerlapping the inner edges of the: sheet strips and rigidly secured to the base.
